B. Agave
C. Sugarbeet
D. Banana

Answer

To solve the question of identifying an example of a biennial and monocarpic plant from the given options (Wheat, Agave, Sugar Beet, Banana), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Biennial Plants**: These plants complete their life cycle in two years. They typically grow in the first year and flower and produce seeds in the second year.
- **Monocarpic Plants**: These plants flower only once in their lifetime and then die.

2. **Analyze the Options**:
- **Wheat**: This is an annual plant, meaning it completes its life cycle in one year. It is not biennial or monocarpic.
- **Agave**: This plant is a monocarpic plant, but it is not biennial. It can take several years to flower but only flowers once in its lifetime.
- **Sugar Beet**: This plant is a biennial plant that flowers in its second year and is also monocarpic because it flowers only once and then dies.
- **Banana**: This plant is also monocarpic, but it is not biennial as it can produce fruit in a single growing season.

3. **Identify the Correct Answer**:
- From the analysis, **Sugar Beet** is the only plant that fits both criteria of being biennial (takes two years to complete its life cycle) and monocarpic (flowers only once).

### Conclusion:
The correct answer is **Sugar Beet**.
